The Museum's massive archaeological collection results from federally mandated cultural resource management projects and myriad projects conducted by university faculty and students. The Museum has also long functioned as a repository for collections donated by members of the Missouri Archaeological Society, as well as for other personal archaeological collections. The majority of the Museum's archaeological holdings are managed by the American Archaeology Division's Curation office. In addition to the Missouri material, the Museum also holds small collections of archaeological material from other states and regions of the world, type and teaching collections, and the renowned Eichenberger collection of expert replicas of many of the world's most significant archaeological pieces.
